Product Engineering

While on-board electronics have become increasingly important in a range of sectors (motoring, rail, aeronautics, etc.), product development has become more complex to take increasingly stringent constraints into account: space saving and lighter weight, improved results, increased strength, etc.

Thanks to its work, Astek has expert knowledge in the precise means and methods required to engineer the most complex products.

High-performance scientific computing

For many years, Astek has developed expertise in the field of high-performance computing and scientific simulation with high-level skills in applied mathematics and physical and computing phenomena.

Modelling and simulation

We carry out complex scientific studies, including specific developments incorporating particular physical phenomena for many industries : aeronautics, automotive, nuclear and oil and gas.


Developing a tool to predict engine lifetimes: Compressible, combustion, two-phase, liquid-film CFD, etc.


Developing combustion simulation models for petrol and diesel engines.


Creating new models to represent industrial installations and changes in line with new parameters arising from going from UO3 to UF4 at the Pierrelatte power plant moving bed furnaces.


Modelling and simulating atmospheric re-entry for space debris and launchers.

Thermal analysis

Thermal analysis is a key element in sizing products developed in a constrained environment. With its expertise in simulation and high-performance computing, Astek has made this one of its main skills areas.

  • Thermal studies on satellite payloads during atmospheric launch; thermal studies on launcher fairing
  • Vehicle engine modelling and thermal validation: engine cooling, vehicle thermal reliability, thermal reliability of hybrid engine-specific components, thermal testing

Fluid and thermodynamic studies

Fluidic and thermodynamic studies require skills in computing, modelling and simulation. Over many years, Astek has developed advanced knowledge in this area, particularly in the energy, motoring and aerospace sectors, with special expertise in two-phase and multiphase flow.


  • Modelling nozzle flow
  • Monitoring fluid and hydromechanical system developments in civil aircraft: analysing possible malfunctions and taking these into account for aircraft maintenance procedures

Petrol and diesel engines

Astek uses its skills in scientific, fluidic and thermodynamic computing to develop expertise across the entire combustion engine development cycle:

  • Injection systems
  • Engine control strategy
  • Model simulation and validation
  • Development
  • Bench and vehicle tests, calibration
  • Production

Hybrid engines

Thanks to its expertise in electrical energy storage, Astek is involved in designing, developing and producing hybrid engines for the motoring sector.

Structural calculation, sizing, materials

With its skills in mathematics, modelling, simulation and thermal science, Astek has developed expertise covering all structural calculation issues:

  • Vibration analysis
  • Thermomechanics
  • Nonlinear calculation
  • Fast dynamics
  • Structure strength

In industries as varied as aeronautics, space and motoring, our work covers all phases of project development: conceptual design, justification, drawing up certification files and even production support.

Given the ever-higher demands in terms of weight, strength and shaping, Astek’s expertise in composite materials enables our experts to meet client challenges by optimising mechanical performance.

Digital design and mock-ups

Astek also has strong skills in mechanical design, digital mock-up management and product lifecycle management, using various tools:

  • Computer Aided Design
  • Mock-up integration
  • Clash analysis
  • Product configuration management
  • Product data management
  • Product lifecycle management
